AUTOMATIC GREASE-CUP.

SPECIFICATION forming part of Letters Patent No, 312,204, dated February 10, 1885 l Application filed Maylfl, 15384. (No model.)

To all whom, it may concern:

Be it known that I, JOHN A. Honour, of De- .troit,.county of \Vayne, State of Michigan,

and useful Improvement I have invented anew in Automatic Grease'Oups; and I declare the following to be a full, clear, and enact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accom panying drawings, which form apartof this specificat-ion.

My invention consists in the combination of devices and appliances hereinafter specified, and more particularly pointed out in the c'aims. y

In the drawings, Figure 1 is a vcrticalsection of a device embodying lny invention.-

Figs. 2 and 3 are variations.

My invention relates to an automatic greasecup adapted to feed the grease continuously.

lIeretofore grease-cups as commonly-con structed haverequired the attention of the attendant to see that they are working properly and to apply pressure from time to time as it may beneeded. in practice it has been-found tliatin certain locations it has been impracticable to apply the necessary pressure while machinery is in motion-as, for instance, a cup connected with a cranRpm-necessitating a stoppage of the. machinery for this purpose.

It is the object of my invention to overcome these difficulties, and to construct a cup that shall feed continuously and automatically without requiring such attentioini I accomplish my object as follows:

As illustrated in the accompanying drawings, A represents the cup. 4

B represents any suitable cap, adapted to be engaged upon the cup. This cap may be engaged upon the cup by screw-connections, or it may be engaged thereon in any other suitable wayas, forinstance, by a catch or ratchet 1 mechanism.

I would have it understood that I do not limit myself to any specific way of securing the cap in place upon the cup.

0 is a movable plate, provided in any suitable manner with an .air-tightjoint at its periphery. As shown, the plate is cut away I upon its edge to receive a suitable packing to its rear in the chamber F. 'It

make the joint air-tight.

a is the outlet-orifice of the cup. The operation of the device is as follows: The cap being removed, the cup is filled with 5 grease. As the plate 0, located within the cap, is forced inward, it is evident that a quantity of air will be confined and compressed in will be seen, therefore, that as the grease feeds from tlze 6 cup the expansion of the compressed air in the rear of the plate 0 will exert a constant press are upon the grease to force it from the cup, this action being automatic. The construc tion necissary to secure this compression of 6 air may be modified in many ways. As shown in Fig. 1, an additional plate, 0, may be employed, connected to the plate G by an intervening stem, 0 in any proper manner. in order to extend the pressure of the air to a 7 greater distancein the cup. So, also, as shown in said figure, an additional movable plate, D, may be employed in connection with the plate 0 or plates G and C, said partition D having an air-tight connection in the cap, and pro- 7 vided with a screw-cut st.em,D',ta-pped through the cap, by. means of which the compression may be increased in the rear of the plate 0; or, moreover, as shown in- Fig. 3, the plate 0 may be dispensed with entirely, preferred, 8 andthe cap be provided with any suitable air; pump, E, having its piston E extending through the top of the cap, the construction being such that air may be forced into the top of the cap, and thereby be compressed in the 8 compressedti r chamber F, the force oftthe air being exerted directly on the contents of the cup, although an intervening partition may be located above the contents, if it should be found desirable. I prefer, also, to secure upon the nozzle of the cup any suitable regulatingvalve, as shown at E. The rateof feed may be regulated, if desired, by means of the valve: stem. I design to employ the cup either witlr or without a regulating-vz'tlve, as may bepreferred. I

What I claim is-"- 1. The combination of a grease'cup. a cap adjustablysecured thereon and provided with a movable partition, and additional mechan- I to compress the air above the contents of the cup, substantially as described.

4. The combination, with a grease-cup having a removable cap and an air-chamber above the contents of the cup, of an air-pump located in the cap to compress the air above the contents of the cup, substantially as described.

- 5.. A grease-cup provided with an air-pump adapted to pump air into the cup-and to compress the same-above the contents of the cup, and a valve for regulating the outflow from the cup, substantially as described.

v 6. The combination, with a grease-cup, of a ism for compressing the air above the particap adj u stably secured thereon, said cap pro vided with a movable plate having an air-tight connection in said'cap, and in connection therewith a movable plateadapted to be located over the contents of the cup, said plates hav- Y ing a connection whereby the expansion of the air behind the plate in the cap will exert a pressure upon the contents of the cup, and mechanism for compressing air above the plates, substantially as described. 7

'7. The combination, with a grease-cup, of a cap adapted to be adj ustably secured thereon, said cap provided with a compressed-air ch amber, said cup provided with a regulating-valve, substantially as described. In testimony whereof I sign this specification in the presence of two witnesses.
